SPECIFICATION forming part of Letters Patent'No. 422,327, dated February 25,-1 890.

' Application filed March 26, 1889.

To aZZ whom it may concern:

Be it known that I, ADOLF ODKOLEK, freiherr von Augezd, captain of horse in the Austrian army, a subject of the Emperor of Austria, residing at Vienna, in the province of Lower Austria, in the Empire of Austria- Hungary, have invented certain new and usef ul Improvements in Magazine Fire-Arms; and I do hereby declare the following to be'a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Referring to the drawings, Figurel is a longitudinal axial sectional elevation of so much of a breech-loading gun as will be necessary to illustrate my invention, the parts being shown in their respectivepositions after firing. Fig. 2 is a like view showing the parts in their respective positions when the breech-bolt is drawn back and the receiver open to receive a fresh cartridge. Fig. 3 is a top plan View of the sliding trigger-guardplate or bar,percussion-firing mechanism, and the breech-bolt-locking devices, the pinion for imparting motion to the bolt being shown in section. Figs. 4, 5, and 6 are sections takeh, re-

spectively, on lines 00 00, 0000, and x m of Fig. 1.

Fig. 7 is a detail view of the locking-lever for locking the trigger-guard plate or bar to the stock. Fig. 8 is a longitudinal section of the gun, part thereof and the slidingbreech-b'olt being shown in elevation, the bolt operating and firing mechanisms being removed, showing the construction of the receiver and bolt.

medium of the trigger-guard; in the com bination, with a boltgun, of a percussionfiring mechanism comprising a hammer and the necessary mechanism for locking said hammer into position for firing, and releasing the same in firing in contradistinction to the spring-actuated firing-pin usually employed in bolt-guns; in mechanism for auto matically placing the firing mechanism in position for firing and simultaneously therewith loading the gun for firing; in structural features whereby the entire operative or actuating mechanism may be bodily and readily removed from the gun, and in certain structural features and combinations of parts A and mechanisms, substantially as hereinafter fully described and claimed.

The" invention further consists in the combination, with a gun of the class described, of a magazine adapted to be applied to one side of the receiver and provided withuneans for delivering the cartridges from above into said reservoir, substantially as hereinafter fully described and claimed.

In the drawings, B indicates the barrel; S, the stock, and R the receiver, which, as more plainly shown in Fig. 8, is provided with a chamber for the reception of the gun-lock and breech -bolt operating mechanism, a slot '1' being formed at the front end of said chamber for the passage of the hammer in firing,

as usual, into the forward end of the receiver.

The chamber in the receiver is closed at bottom by a lock-plate B, that is provided with a longitudinal slot b, and is secured at its forward end to the stock by means of an overlapping screw 71, and by means of forwardly-inclined lugs 1), bearing against corresponding shoulders h, formed at the forward end of the receiver-chamber. At its rear end the lock-plate B is secured to the stock by means of a screw 72, that screws into the post 7*, depending from the tang of the receiver R, so that by unscrewing the screw h and simply loosening the screw k the lock-plate B can be removed, and with it the lock and breech-bolt operating mechanisms. The hammer and its spring, the sear and its spring, and the pinion that imparts motion to the breech-bolt are carried by the lockplate B.

The hammerE is pivoted in bearings formed in a post p and has an arm 6 and a shoulder against which bears the main or hammer spring 6 which is connected by tongue-andgroove joint with a bracket or post p. I

The sear E is pivoted in bearings formed in a post p and provided with an arm 6 upon which bears the free end of the sear-spring connected with the lock-plate B by a tongueand-groove joint, said sear having a second arm e, adapted to engage the full-cock notch formed in a tumbler E rigidly secured to the hammer-pivot or forming an integral part of the hammer E. Finally, the pinion b is journaled in bearings formed in a post p By connecting the main or hammer spring a and the sear-spring c with their supports, as described, said springs can be readily removed in case of breakage and others substituted.

The posts that support the main or hammer spring 6 and the hammer E are arranged to straddle the slot b in the lock-plate B and serve as guides for the movements of the sliding trigger-guard plate or bar B, which lies between the lugs of said posts, while the post which supports the pinion is arranged on one side of the said slot.

The trigger-guard A is secured to a slide bar or plate B, the arm a of the trigger T pivoted to the guard projecting through the slot b in lock-plate B, said trigger-guard serving as a handle to plate B for imparting horizontal motion thereto.

The rear end of the trigger-guard plate B is constructed in the form of a toothed rack b and is adapted to gear with the pinion b which latter is in perpetual gear with a toothed rack (1, formed on or secured within a suitable recess formed in the cylindrical breech-bolt D, that is adapted to slide to and fro in the receiver B.

As more plainly shown in Fig. 2, the toothed rack d is formed with an inclined bearingface at its forward end that abuts against a corresponding shoulder in the breech-bolt, while at its rear end, the contacting-faces incline in a reverse direction, so that a single screw (1 screwed through the rear wall of the bolt, is all that is required to lock the toothed rack in position.

It is obvious that if the triggerguard plate B is moved in one direction or toward the barrel the breech-bolt D will move in a reverse direction to open the breech and receiver for the reception of a fresh cartridge, at the same time ejecting the empty shell, if any, through the medium of the extractor d arranged in the usual manner, as shown in Figs. 2,11, 14, 14, and 14. A motion of the trigger-guard plate in a reverse direction will, on the contrary, cause the breech-bolt D to move forward and close the breech, at the same time carrying a cartridge introduced into the receiver into the breech-chamber. On a pin 0, secured to post p, is fulcrumed a lever 0, one arm 0 of which lies in a notch 1), formed by two inclined projections or teeth on the trigger-guard plate B. The other arm of lever O has a stud 0 that projects into a horizontal slot 0 formed in an ear on the under side of a locking block 0, that is adapted to slide in the slot or housing R, hereinbefore referred to, and into a recess (1, Fig.8, formed in the under side of the breechbolt D,when said bolt is in a position to close the breech of the gun, as shown in Fig. 1. As the trigger-guard plate moves forward'the arm 0 of lever O moves out of the notch 17' over the rear tooth or projection, allowing the locking-block O to drop down out of the recess d in the breech-bolt D, so as to allow said bolt to move backward.

As an alternative device for operating the locking-block O, the trigger-guard plate B may be provided-with an inclined face 1 ,which may act directly upon the said locking-block by passing under the same to lift it into the recess d of the breech-chamber on the backward movement of the plate B, as shown in Fig. 15; or said incline may operate on a lug or proj ection t" on the side of the actuating-leverO, as shown in Fig. 16. In the former construction the actuating or lifting lever serves as a guide for the block, and also serves to prevent the block from binding in its housing on being lifted by the incline 'i; or said lever may be dispensed with, the blockfalling down of its own weight as the trigger-guard plate moves forward. In the construction shown in Fig. 16 the lowering of the block is eifected by the incline Z) acting upon lever O, as above described. The locking-block may also be so arranged as to pass in rear of the breech-bolt when the latter is in its normal position to close the breech, and the lifting-lever C may be fulcrumed 011 a pin or stud secured to the receiver instead of pivoting the lever to a post on the lock-plate B.

The trigger-guard plate B has a greater range of motion than-the breech-bolt, and the toothed rack 11 has preferably a less number of teeth than the rack d of said bolt, so that the said rack 12 will move out of gear with the pinion b when the trigger-guard plate is about to reach the limit of its rearward-motion, and the extent of forward motion of the plate B before the said toothed rack engages the pinion is sufficient to'first disengage the locking-block G from the breechbolt D, in the manner described, the engagement of the toothed rack 19 with the pinion taking place immediatelyv after the block 0' has cleared the recess 61 in the breech-bolt.

To the trigger-guard plate B is pivoted a lever a, upon the downturned rear end of which bears the detent or actuating arm a of the trigger T, while the forward upturned end of said lever is adapted to engage the arm e of the sear, when the parts are in position for firing, as shown in Fig. 1, wherein the firing mechanism is shown in its position after the sear E has been released from the full-cock notch e in tumbler It through the medium of said lever a. l

The hammer E is brought to a full-cock on the forward movement of the trigger-guard plate B through the medium of a projection b secured to plate B near its forward end, the vertical face of said projection engaging the arm 6 of the hammer E and turning it against the stress of its spring 6 and with it the tumbler E againstthe stress of the searspring 6 The projection b is curved or inclined rearwardly, so as to slide under the arm 6 of the hammer when the trigger-guard plate B is moved back, leaving the hammer at full-cock. Before the plate B reaches the limit of its backward motion the toothed rack 12 as previously explained, is disengaged from the pinion b and simultaneously therewith or immediately thereafter the vertical face of the notch b engages the arm 0 of lever 0, moving the same downward, while the arm of said lever that; carries the block 0' is moved upward and into the recess 01 of the breech-block D, the gun being then ready for firing.

During the reciprocating motion of the trigger-guard plate B the following operations take place: On the forward movementof the platesay immediately after firingthe locking-block O is firstdisengagedfromthebreechbolt. The toothed rack b on said plate is next brought into gear with the pinion b The breech-bolt D is moved backward,the extractor d throwing out the empty shell. The shoulder b on plate B next engages the hammer-arm e and brings the hammer to a full-cock, as described, the plate being moved forward until the said shoulder 11* abuts against a stop-shoulder formed in the stock, (see Fig. 2,) at which time the breech-bolt will also have reached the limit of its backward motion, completely clearing the top opening in the receiver for the reception of a cartridge, which may be introduced by hand or fed thereto, as will be presently described. On the backward motion of the plate B and the simultaneous forward motion of the breech-bolt D and cartridge all of the remaining mechanism will remain in the position in which itwas brought during the forward movement of the plate B until the said plate has moved back sufficiently to disengage the toothed rack from pinion b ,when the lever that carries the sliding block will be tilted to move the locking block 0 into the recess 01 in the breech-bolt D, which has then reached the limit of its forward motionand has carried the cartridge into the breech, when, by pressing the trigger, the intermediate lever a will be tripped and its forward upturned end will act upon the sear E to release the hammer, as above described. During these movements of the trigger-guard plate it is not necessary that the trigger be released. In fact, such trigger may be kept under pressure all the time from the time the gun is first fired, so that the subsequent firing will take place automatically,

for as soon as the locking-block has moved into the recess of the breech-block D the upturned forward end will engage the sear and release the hammer. It will be readily seen that the gun can be more rapidly .fired than locking-notch a in the lock-plate B, and is held in engagement with said notch by a spring a secured to the trigger-guard, the free end of said spring acting upon the forward arm of the lever. The locking-nose of the catch and the recess in the plate being of ourvilinear form a slight push on the triggerguard will readily unlock the same in loading.

When the gun is not in use, to avoid an accidental discharge when loaded and ready for firing, I provide a sliding sleeve a mounted on the trigger-guard and adapted to slideunder the locking-lever A and abut against the back of the trigger, thereby preventing the latter from tripping the intermediate acthating-lever a to release the .firing mechanism and at the same time preventing the spring-catch being disengaged from the lock ing-notch.

The gun constructed as described may be used as a repeating-gun, and is provided with means for connecting a magazine with the receiver. These means may be of any suitable character, or they may consist, as shown, in the overhanging lip or ledge G,the grooves IIS g, formed on opposite sides thereof, and a. I

spring-actuated stud g, (see Fig. 11,) for use with the magazine F, (shown in Figs. 10, 12,
